Application iiled June 29, 1900. Serial No. 22,091. (No model.)

To all whom t may concern:

Be it known that I, EDWARD E. DAVIS, a citizen of the United States, residing at New York, in the county of New York and State of New York,havein vented certain new and useful Improvements in Lubricators,of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to oil-cups forlubricating purposes; and its Objectis the construction of a cup which will obviate the necessity of using tools or complicated mechanism in the feeding, controlling, and shutting off of the supply of oil to the parts to be lubricated and to substitute for such tools and mechanism a device which needs only the raising and lowering of the cover of the oil-cup by hand to regulate the iiow of the oil.

To this end my invention consists of an adjustable cup or cover provided with a shutoff attachment which operates by the force of gravity alone to cut off the How of oil, as hereinafter described and particularly claimed.

My invention is illustrated in the accompanying drawings, in which- Figure l is an exterior View in elevation showing the cover in position when the oil is flowing; Fig. 2, a similar View showing the cover in position when the tlow of the oil is cut olf; and Fig. 3, atransverse sectional View in elevation ot' the cover and cup, showing cut-oit means in the cover, the cup, wick-tube, and wick and the position of the cup when the fiow of oil is cut off.

Referring to the drawings, A is a closed top cover provided with an inner central cone-shaped projecting plug B. One side of the downwardly-extending Wall of the cover is provided with two open slots C D, the slot D being longer than the slot C.

E is the oil-cup, provided with a central wick-tube F and wick G. The body of the oil-cup Eis also provided on its outer surface with a pin or boss H and at its base with the usual circumferential ange I.

Referring now particularly to Fig. l, which shows the cover and cup in position when the capillary How of the oil is continuing, it will be noticed that in such position the pin I-I is in the shorter slot C, whereby the cover is held above the base-flange Iand the closingplug B is held above and free from contact with the top of the wick-tube F.

In the position of the parts as indicated in Figs. 2 and 3 the pin or projection H of the cover is in the longer slot D, in which position the conical plug B extends into the wicktube F, said plug being forced into and heldin said tube by the entire weight of the cover, thus pressing the wick tightly against the walls of the tube and effectually shutting ott and preventing the dow of the oil through the wick.

It will be noticed that in order that the entire weight of the cover shall be on the wicktube and wick the slot D is of such length and the position ot' the boss or pin H is such that when these two parts are engaged the cover will be held above the iiange I. The cover is operated by hand, and for convenience the shorter slot C has stamped over it the letter O to indicate that when the pin His in that slot the cup is open, and over the longer slot D the letter is stamped to indicate that when the pin H is in that slot the cover is down and the cup closed and the oil cut O. It will be seen that all the operator has to do to open or close the wick-tube is to raise the cover by hand and turn it to the right or left, so as to permit the slot C or the slot D to register with the pin H, as it may be desired to either close or open the tube, and then let the cover fall by its own weight.

It will be noticed also that the wick-tube F forms a seat for the conical plug` B, and for this purpose the wick-tube has a slightinner annular bevel l) at its top, so that the conical plug might form a valve for closing and cutting oft' the supply of oil should the wick be dispensed with and the oil be otherwise fed into the central tube. In either or all cases the tube F is a feeding-tube. It will be observed also that as the cut-oft' is effected by the weight of the cover as it is dropped and rests on the wick the cone-shaped plug is not actually necessary to create sufficient pressure, although a preferable device, as such suiicient pressure might be obtained by the weight alone of the cover on the wick or by a `flat or rounded plug or projection in place of the conical plug, or the cover may be pro vided in place of the plug with a flat surface,

With a seat for the ytop of the Wick-tube or' central port F. It is also evident that the two slots might be merged into one, as a bayonet-slot, by which the same operation might be had.

Y Having thus described my invention, what I claim is- 1. An oil-cup composed of a body for the oil and having an inner feed-tube, in combination with a sliding, gravity-pressure cut-oft cover having an inner part to engage with the top of thetube to Shut off the feed of oil, substantially as described.

2. In an oil-cup the body provided With an outside projection and an inner oil-feeding tube in combination with a cover having its therethrough or to be held out of said engagement, substantially as described.

3. In an oil-cup, the body provided with an inner oil-feeding wick-tube, and an outside projection in combination with a cover provided With an inside conically-shaped plug and with outside slots, whereby the said cover is adapted 'lo be raised and rested on said projection through one of said slots, and lowered on the said projection through the other of said slots, the said conical plug engaging With said Wick-lube when so lowered to cut off the flow of the oil, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

EDWARD E. DAVIS.
